A pumping system is required that will deliver at least 50,000 GPM against a head of 100 ft is needed for a water ride. The system schematic is given below. Note that the loss coefficient for the pumps accounts for the losses in piping connecting multiple pumps. Use Gould pumps to satisfy this requirement. Submit your loss curve superimposed on the pump curves for the selected pumps in your Excel file. Determine the following. a. The pumps (all the same) to satisfy this requirement. b.

6. A pump is located 4.5 m to one side of, and 3.5 m above a reservoir. The pump is designed for a flow rate of 6 L s'. For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of the water gage. Determine the smallest standard commercial steel pipe that will give the required performance. pump 4.5 m. 1.8 19=d 3.5 m 7. water 90° elbow
1- Derive an expression for the flow rate q over the spillway shown in figure bellow per foot of spillway perpendicular to the sketch. Assume that the sheet of water is relatively thick, so that surface -tension effects are negligible. Assume also that gravity effects predominate so strongly over viscosity that we can neglect viscosity. H.

CHOICES FOR PIPE 3: A. 733, B.373, C. 133, D. 311 Determine the discharge at pipeline 3 in lit/sec assuming f=0.02 for all pipes. AND PIPE 2
a) Two pipes have a length ? each. One of them has a diameter D, and the other a diameter d.if the pipes are arranged in parallel, the loss of head when a total quantity of water Q flows through them is h, but, if the pipes are arranged in series and the same quantity Q flows through them, the loss of head is H. If ?=?/2, find the ratio of H to h, neglecting secondary losses and assuming the pipe coefficient f has a constant value. b) A pipeline of 0.6m diameter is 1.5km long.To increase the discharge, another line of the same diameter is introduced parallel to the first in the second half of the length.Neglecting minor losses, find the increase in discharge if 4f = 0.04. The head at inlet is 300mm. c) Determine the difference in the elevations between the water surfaces in the two tanks which are connected by a horizontal pipe of diameter 300 mm and a length of 400 mm. The rate of flow of water through the pipe is 300 litres/s. Consider all losses and takef=0.008. d) Water at 20°C is…
